The ongoing process of globalization leads to a huge demand for highly scalable applications. The Peer-to-Peer (P2P) technology enables an arbitrary large number of users to participate and contribute to distributed services like content distribution or collaboration. With P2P, the intelligence is shifted from centralized instances to the edges of the Internet. This shift is supported by the wi...

The emergence of application-layer overlay networks has inspired the development of new network services and applications. Research on overlay networks has focused on the design of protocols to maintain and forward data in an overlay network, however, less attention has been given to the software development process of building application programs in such an environment. Clearly, the complexit...

OBJECTIVES Investigate the recurrence of chronic otitis media after primary and revision myringoplasty, compare long-term anatomic and audiologic results of underlay and overlay myringoplasty, and examine the prognostic factors. STUDY DESIGN Retrospective study. PATIENTS Approximately 1,040 adult patients with chronic simple otitis media undergoing a myringoplasty (overlay and underlay) by ...

Application-layer multicast supports group applications without the need for a network-layer multicast protocol. Here, applications arrange themselves in a logical overlay network and transfer data within the overlay. In this paper, we present an application-layer multicast solution that uses a Delaunay triangulation as an overlay network topology. An advantage of using a Delaunay triangulation...

Application-layer overlay networks have been proposed as an alternative method to overcome IP-layer path anomalies and provide users with improved routing services. Running at the application layer, overlay networks usually rely on probing mechanisms for IP-path performance monitoring and failure detection. Their service performance is jointly determined by their topology, parameters of probing...

Lately, peer-to-peer overlay networks and their ability to reflect the underlying network topology have been a focus in research. The main objective has been to reduce routing path lengths, stretched by the overlay routing process. In most solutions developed, a kind of fixed infrastructure in the form of so called landmarks or excessive message exchange are necessary to guarantee good overlay ...

It is a widely accepted notion that the native layer of the current Internet has begun to stagnate in terms of the services offered. Consequently, overlay networks have gained attention as a viable alternative to overcome functionality limitations of the Internet. A common approach to overlay network design holds the native network inviolable, implying that the overlay has to take on all the ta...

For a peer-to-peer (P2P) system holding massive amount of data, efficient search for resources (such as data or services) is a key determinant to its scalability. This paper presents semantic small world (SSW), an overlay network and index structure for semantic based P2P search. By dynamically clustering peer nodes in a semantic space based on the semantics of their data and organizing the clu...
